[PATCH AUTOSEL 6.6 01/13] cifs: Correctly set SMB1 SessionKey field in Session Setup Request

by Sasha Levin

From: Pali Rohár <pali(a)kernel.org> [ Upstream commit 89381c72d52094988e11d23ef24a00066a0fa458 ] [MS-CIFS] specification in section 2.2.4.53.1 where is described SMB_COM_SESSION_SETUP_ANDX Request, for SessionKey field says: The client MUST set this field to be equal to the SessionKey field in the SMB_COM_NEGOTIATE Response for this SMB connection. Linux SMB client currently set this field to zero. This is working fine against Windows NT SMB servers thanks to [MS-CIFS] product behavior <94>: Windows NT Server ignores the client's SessionKey.

Signed-off-by: Pali Rohár <pali(a)kernel.org> Signed-off-by: Steve French <stfrench(a)microsoft.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- Based on my comprehensive analysis of both the commit message and code changes, examining the current kernel tree context: **YES** ## Extensive Analysis ### **Nature of the Fix** This is a **specification compliance fix** for SMB1 protocol handling. The commit addresses a clear violation of the MS-CIFS specification section 2.2.4.53.1, which mandates that the SessionKey field in SMB_COM_SESSION_SETUP_ANDX Request must be set to the value from the SMB_COM_NEGOTIATE Response. ### **Code Changes Analysis** **1. Structural Changes (Low Risk)** - **cifsglob.h**: Adds `__le32 session_key_id` to `TCP_Server_Info` structure - minimal ABI impact as this is kernel-internal - **cifspdu.h**: Corrects endianness annotations from `__u32` to `__le32` - pure annotation fix, no behavioral change **2. Functional Changes (Contained and Safe)** - **cifssmb.c**: Captures SessionKey from negotiate response (`server->session_key_id = pSMBr->SessionKey`) - simple field assignment - **sess.c**: Sets SessionKey in session setup request (`pSMB->req.SessionKey = server->session_key_id`) - follows specification requirement ### **Risk Assessment** **Minimal Regression Risk:** - Changes are isolated to SMB1 legacy protocol code - Current behavior (setting SessionKey to zero) works with Windows NT due to MS- CIFS product behavior <94> - New behavior follows specification exactly, improving compatibility with non-Windows SMB1 servers - No security implications - purely a protocol compliance improvement **Code Maturity:** - SMB1 session setup code is very mature and stable - Limited recent changes in this area except compatibility fixes - Well- understood code path with clear specification backing ### **Backport Suitability Criteria Met** **1. Important Bug Fix:** ✅ Fixes protocol specification violation that could cause compatibility issues with strict SMB1 implementations **2. Small and Contained:** ✅ Four minimal changes across related files, all implementing the same specification requirement **3. Clear Side Effects:** ✅ No side effects beyond fixing the specification compliance issue **4. No Architectural Changes:** ✅ Simple field additions and assignments, no structural changes **5. Non- Critical Subsystem:** ✅ Legacy SMB1 protocol code, deprecated since 2017 **6. Minimal Risk:** ✅ Maintains backward compatibility while improving forward compatibility **7. Stable Tree Rules Compliance:** ✅ Important compatibility bugfix with minimal regression risk ### **Comparison to Similar Commits** This commit closely matches the pattern of **Similar Commit #3** and **Similar Commit #5** (both marked YES for backporting): - Protocol compliance improvements - Session setup related fixes - Clear specification backing - Minimal, contained changes - Authored by maintainers (Steve French involvement) ### **Conclusion** This commit represents an ideal stable backport candidate: a clear specification compliance fix with minimal code changes, no security implications, and improvement in interoperability. The fix ensures Linux kernel SMB client properly follows MS-CIFS specification, which is valuable for enterprise environments using diverse SMB1 server implementations. fs/smb/client/cifsglob.h | 1 + fs/smb/client/cifspdu.h | 6 +++--- fs/smb/client/cifssmb.c | 1 + fs/smb/client/sess.c | 1 + 4 files changed, 6 insertions(+), 3 deletions(-) diff --git a/fs/smb/client/cifsglob.h b/fs/smb/client/cifsglob.h index 39117343b703f..1f3451202fe8d 100644 --- a/fs/smb/client/cifsglob.h +++ b/fs/smb/client/cifsglob.h @@ -739,6 +739,7 @@ struct TCP_Server_Info { char workstation_RFC1001_name[RFC1001_NAME_LEN_WITH_NULL]; __u32 sequence_number; /* for signing, protected by srv_mutex */ __u32 reconnect_instance; /* incremented on each reconnect */ + __le32 session_key_id; /* retrieved from negotiate response and send in session setup request */ struct session_key session_key; unsigned long lstrp; /* when we got last response from this server */ struct cifs_secmech secmech; /* crypto sec mech functs, descriptors */ diff --git a/fs/smb/client/cifspdu.h b/fs/smb/client/cifspdu.h index ca33f6cd6a800..763178b774542 100644 --- a/fs/smb/client/cifspdu.h +++ b/fs/smb/client/cifspdu.h @@ -557,7 +557,7 @@ typedef union smb_com_session_setup_andx { __le16 MaxBufferSize; __le16 MaxMpxCount; __le16 VcNumber; - __u32 SessionKey; + __le32 SessionKey; __le16 SecurityBlobLength; __u32 Reserved; __le32 Capabilities; /* see below */ @@ -576,7 +576,7 @@ typedef union smb_com_session_setup_andx { __le16 MaxBufferSize; __le16 MaxMpxCount; __le16 VcNumber; - __u32 SessionKey; + __le32 SessionKey; __le16 CaseInsensitivePasswordLength; /* ASCII password len */ __le16 CaseSensitivePasswordLength; /* Unicode password length*/ __u32 Reserved; /* see below */ @@ -614,7 +614,7 @@ typedef union smb_com_session_setup_andx { __le16 MaxBufferSize; __le16 MaxMpxCount; __le16 VcNumber; - __u32 SessionKey; + __le32 SessionKey; __le16 PasswordLength; __u32 Reserved; /* encrypt key len and offset */ __le16 ByteCount; diff --git a/fs/smb/client/cifssmb.c b/fs/smb/client/cifssmb.c index b91184ebce02c..096ea62e87ea9 100644 --- a/fs/smb/client/cifssmb.c +++ b/fs/smb/client/cifssmb.c @@ -479,6 +479,7 @@ CIFSSMBNegotiate(const unsigned int xid, server->max_rw = le32_to_cpu(pSMBr->MaxRawSize); cifs_dbg(NOISY, "Max buf = %d\n", ses->server->maxBuf); server->capabilities = le32_to_cpu(pSMBr->Capabilities); + server->session_key_id = pSMBr->SessionKey; server->timeAdj = (int)(__s16)le16_to_cpu(pSMBr->ServerTimeZone); server->timeAdj *= 60; diff --git a/fs/smb/client/sess.c b/fs/smb/client/sess.c index f04922eb45d4c..a7ece67ee9630 100644 --- a/fs/smb/client/sess.c +++ b/fs/smb/client/sess.c @@ -680,6 +680,7 @@ static __u32 cifs_ssetup_hdr(struct cifs_ses *ses, USHRT_MAX)); pSMB->req.MaxMpxCount = cpu_to_le16(server->maxReq); pSMB->req.VcNumber = cpu_to_le16(1); + pSMB->req.SessionKey = server->session_key_id; /* Now no need to set SMBFLG_CASELESS or obsolete CANONICAL PATH */ -- 2.39.5

[PATCH] hwmon: (ftsteutates) Fix TOCTOU race in fts_read()

by Gui-Dong Han

In the fts_read() function, when handling hwmon_pwm_auto_channels_temp, the code accesses the shared variable data->fan_source[channel] twice without holding any locks. It is first checked against FTS_FAN_SOURCE_INVALID, and if the check passes, it is read again when used as an argument to the BIT() macro. This creates a Time-of-Check to Time-of-Use (TOCTOU) race condition. Another thread executing fts_update_device() can modify the value of data->fan_source[channel] between the check and its use. If the value is changed to FTS_FAN_SOURCE_INVALID (0xff) during this window, the BIT() macro will be called with a large shift value (BIT(255)). A bit shift by a value greater than or equal to the type width is undefined behavior and can lead to a crash or incorrect values being returned to userspace. Fix this by reading data->fan_source[channel] into a local variable once, eliminating the race condition. Additionally, add a bounds check to ensure the value is less than BITS_PER_LONG before passing it to the BIT() macro, making the code more robust against undefined behavior. This possible bug was found by an experimental static analysis tool developed by our team.

[PATCH v1] mm: Close theoretical race where stale TLB entries could linger

by Ryan Roberts

Commit 3ea277194daa ("mm, mprotect: flush TLB if potentially racing with a parallel reclaim leaving stale TLB entries") described a theoretical race as such: """ Nadav Amit identified a theoritical race between page reclaim and mprotect due to TLB flushes being batched outside of the PTL being held. He described the race as follows: CPU0 CPU1 ---- ---- user accesses memory using RW PTE [PTE now cached in TLB] try_to_unmap_one() ==> ptep_get_and_clear() ==> set_tlb_ubc_flush_pending() mprotect(addr, PROT_READ) ==> change_pte_range() ==> [ PTE non-present - no flush ] user writes using cached RW PTE ... try_to_unmap_flush() The same type of race exists for reads when protecting for PROT_NONE and also exists for operations that can leave an old TLB entry behind such as munmap, mremap and madvise. """ The solution was to introduce flush_tlb_batched_pending() and call it under the PTL from mprotect/madvise/munmap/mremap to complete any pending tlb flushes. However, while madvise_free_pte_range() and madvise_cold_or_pageout_pte_range() were both retro-fitted to call flush_tlb_batched_pending() immediately after initially acquiring the PTL, they both temporarily release the PTL to split a large folio if they stumble upon one. In this case, where re-acquiring the PTL flush_tlb_batched_pending() must be called again, but it previously was not. Let's fix that. There are 2 Fixes: tags here: the first is the commit that fixed madvise_free_pte_range(). The second is the commit that added madvise_cold_or_pageout_pte_range(), which looks like it copy/pasted the faulty pattern from madvise_free_pte_range(). This is a theoretical bug discovered during code review.

[PATCH] drm/xe/bmg: fix compressed VRAM handling

by Matthew Auld

There looks to be an issue in our compression handling when the BO pages are very fragmented, where we choose to skip the identity map and instead fall back to emitting the PTEs by hand when migrating memory, such that we can hopefully do more work per blit operation. However in such a case we need to ensure the src PTEs are correctly tagged with a compression enabled PAT index on dgpu xe2+, otherwise the copy will simply treat the src memory as uncompressed, leading to corruption if the memory was compressed by the user. To fix this it looks like we can pass use_comp_pat into emit_pte() on the src side. There are reports of VRAM corruption in some heavy user workloads, which might be related: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4495 Fixes: 523f191cc0c7 ("drm/xe/xe_migrate: Handle migration logic for xe2+ dgfx") Signed-off-by: Matthew Auld <matthew.auld(a)intel.com> Cc: Himal Prasad Ghimiray <himal.prasad.ghimiray(a)intel.com> Cc: Thomas Hellström <thomas.hellstrom(a)linux.intel.com> Cc: Akshata Jahagirdar <akshata.jahagirdar(a)intel.com> Cc: <stable(a)vger.kernel.org> # v6.12+ --- drivers/gpu/drm/xe/xe_migrate.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/xe/xe_migrate.c b/drivers/gpu/drm/xe/xe_migrate.c index 8f8e9fdfb2a8..16788ecf924a 100644 --- a/drivers/gpu/drm/xe/xe_migrate.c +++ b/drivers/gpu/drm/xe/xe_migrate.c @@ -863,7 +863,7 @@ struct dma_fence *xe_migrate_copy(struct xe_migrate *m, if (src_is_vram && xe_migrate_allow_identity(src_L0, &src_it)) xe_res_next(&src_it, src_L0); else - emit_pte(m, bb, src_L0_pt, src_is_vram, copy_system_ccs, + emit_pte(m, bb, src_L0_pt, src_is_vram, copy_system_ccs || use_comp_pat, &src_it, src_L0, src); if (dst_is_vram && xe_migrate_allow_identity(src_L0, &dst_it)) -- 2.49.0

[PATCH] LoongArch: vDSO: correctly use asm parameters in syscall wrappers

by Thomas Weißschuh

The syscall wrappers use the "a0" register for two different register variables, both the first argument and the return value. The "ret" variable is used as both input and output while the argument register is only used as input. Clang treats the conflicting input parameters as undefined behaviour and optimizes away the argument assignment. The code seems to work by chance for the most part today but that may change in the future. Specifically clock_gettime_fallback() fails with clockids from 16 to 23, as implemented by the upcoming auxiliary clocks. Switch the "ret" register variable to a pure output, similar to the other architectures' vDSO code. This works in both clang and GCC.

[PATCH] tools/resolve_btfids: Fix build when cross compiling kernel with clang.

by Suleiman Souhlal

When cross compiling the kernel with clang, we need to override CLANG_CROSS_FLAGS when preparing the step libraries for resolve_btfids. Prior to commit d1d096312176 ("tools: fix annoying "mkdir -p ..." logs when building tools in parallel"), MAKEFLAGS would have been set to a value that wouldn't set a value for CLANG_CROSS_FLAGS, hiding the fact that we weren't properly overriding it.

[merged mm-hotfixes-stable] mm-hugetlb-fix-huge_pmd_unshare-vs-gup-fast-race.patch removed from -mm tree

Its filename was mm-hugetlb-fix-huge_pmd_unshare-vs-gup-fast-race.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Jann Horn <jannh(a)google.com> Subject: mm/hugetlb: fix huge_pmd_unshare() vs GUP-fast race Date: Tue, 27 May 2025 23:23:54 +0200 huge_pmd_unshare() drops a reference on a page table that may have previously been shared across processes, potentially turning it into a normal page table used in another process in which unrelated VMAs can afterwards be installed. If this happens in the middle of a concurrent gup_fast(), gup_fast() could end up walking the page tables of another process. While I don't see any way in which that immediately leads to kernel memory corruption, it is really weird and unexpected. Fix it with an explicit broadcast IPI through tlb_remove_table_sync_one(), just like we do in khugepaged when removing page tables for a THP collapse.

[merged mm-hotfixes-stable] mm-hugetlb-unshare-page-tables-during-vma-split-not-before.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/hugetlb: unshare page tables during VMA split, not before has been removed from the -mm tree. Its filename was mm-hugetlb-unshare-page-tables-during-vma-split-not-before.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Jann Horn <jannh(a)google.com> Subject: mm/hugetlb: unshare page tables during VMA split, not before Date: Tue, 27 May 2025 23:23:53 +0200 Currently, __split_vma() triggers hugetlb page table unsharing through vm_ops->may_split(). This happens before the VMA lock and rmap locks are taken - which is too early, it allows racing VMA-locked page faults in our process and racing rmap walks from other processes to cause page tables to be shared again before we actually perform the split. Fix it by explicitly calling into the hugetlb unshare logic from __split_vma() in the same place where THP splitting also happens. At that point, both the VMA and the rmap(s) are write-locked. An annoying detail is that we can now call into the helper hugetlb_unshare_pmds() from two different locking contexts: 1. from hugetlb_split(), holding: - mmap lock (exclusively) - VMA lock - file rmap lock (exclusively) 2. hugetlb_unshare_all_pmds(), which I think is designed to be able to call us with only the mmap lock held (in shared mode), but currently only runs while holding mmap lock (exclusively) and VMA lock Backporting note: This commit fixes a racy protection that was introduced in commit b30c14cd6102 ("hugetlb: unshare some PMDs when splitting VMAs"); that commit claimed to fix an issue introduced in 5.13, but it should actually also go all the way back.

Its filename was alloc_tag-handle-module-codetag-load-errors-as-module-load-failures.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Suren Baghdasaryan <surenb(a)google.com> Subject: alloc_tag: handle module codetag load errors as module load failures Date: Wed, 21 May 2025 09:06:02 -0700 Failures inside codetag_load_module() are currently ignored. As a result an error there would not cause a module load failure and freeing of the associated resources. Correct this behavior by propagating the error code to the caller and handling possible errors. With this change, error to allocate percpu counters, which happens at this stage, will not be ignored and will cause a module load failure and freeing of resources. With this change we also do not need to disable memory allocation profiling when this error happens, instead we fail to load the module.

Its filename was mm-fix-uprobe-pte-be-overwritten-when-expanding-vma.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Pu Lehui <pulehui(a)huawei.com> Subject: mm: fix uprobe pte be overwritten when expanding vma Date: Thu, 29 May 2025 15:56:47 +0000 Patch series "Fix uprobe pte be overwritten when expanding vma". This patch (of 4): We encountered a BUG alert triggered by Syzkaller as follows: BUG: Bad rss-counter state mm:00000000b4a60fca type:MM_ANONPAGES val:1 And we can reproduce it with the following steps: 1. register uprobe on file at zero offset 2. mmap the file at zero offset: addr1 = mmap(NULL, 2 * 4096, PROT_NONE, MAP_PRIVATE, fd, 0); 3. mremap part of vma1 to new vma2: addr2 = mremap(addr1, 4096, 2 * 4096, MREMAP_MAYMOVE); 4. mremap back to orig addr1: mremap(addr2, 4096, 4096, MREMAP_MAYMOVE | MREMAP_FIXED, addr1); In step 3, the vma1 range [addr1, addr1 + 4096] will be remap to new vma2 with range [addr2, addr2 + 8192], and remap uprobe anon page from the vma1 to vma2, then unmap the vma1 range [addr1, addr1 + 4096]. In step 4, the vma2 range [addr2, addr2 + 4096] will be remap back to the addr range [addr1, addr1 + 4096]. Since the addr range [addr1 + 4096, addr1 + 8192] still maps the file, it will take vma_merge_new_range to expand the range, and then do uprobe_mmap in vma_complete. Since the merged vma pgoff is also zero offset, it will install uprobe anon page to the merged vma. However, the upcomming move_page_tables step, which use set_pte_at to remap the vma2 uprobe pte to the merged vma, will overwrite the newly uprobe pte in the merged vma, and lead that pte to be orphan. Since the uprobe pte will be remapped to the merged vma, we can remove the unnecessary uprobe_mmap upon merged vma.

[PATCH] media: rainshadow-cec: fix TOCTOU race condition in rain_interrupt()

by Gui-Dong Han

In the interrupt handler rain_interrupt(), the buffer full check on rain->buf_len is performed before acquiring rain->buf_lock. This creates a Time-of-Check to Time-of-Use (TOCTOU) race condition, as rain->buf_len is concurrently accessed and modified in the work handler rain_irq_work_handler() under the same lock. Multiple interrupt invocations can race, with each reading buf_len before it becomes full and then proceeding. This can lead to both interrupts attempting to write to the buffer, incrementing buf_len beyond its capacity (DATA_SIZE) and causing a buffer overflow. Fix this bug by moving the spin_lock() to before the buffer full check. This ensures that the check and the subsequent buffer modification are performed atomically, preventing the race condition. An corresponding spin_unlock() is added to the overflow path to correctly release the lock. This possible bug was found by an experimental static analysis tool developed by our team.

[PATCH 6.12 1/1] PCI/ASPM: Disable L1 before disabling L1 PM Substates

by Macpaul Lin

From: Ajay Agarwal <ajayagarwal(a)google.com> [ Upstream commit 7447990137bf06b2aeecad9c6081e01a9f47f2aa ] PCIe r6.2, sec 5.5.4, requires that: If setting either or both of the enable bits for ASPM L1 PM Substates, both ports must be configured as described in this section while ASPM L1 is disabled. Previously, pcie_config_aspm_l1ss() assumed that "setting enable bits" meant "setting them to 1", and it configured L1SS as follows: - Clear L1SS enable bits - Disable L1 - Configure L1SS enable bits as required - Enable L1 if required With this sequence, when disabling L1SS on an ARM A-core with a Synopsys DesignWare PCIe core, the CPU occasionally hangs when reading PCI_L1SS_CTL1, leading to a reboot when the CPU watchdog expires. Move the L1 disable to the caller (pcie_config_aspm_link(), where L1 was already enabled) so L1 is always disabled while updating the L1SS bits: - Disable L1 - Clear L1SS enable bits - Configure L1SS enable bits as required - Enable L1 if required Change pcie_aspm_cap_init() similarly.

[PATCH 6.12.y] block: fix adding folio to bio

by alvalan9＠foxmail.com

From: Ming Lei <ming.lei(a)redhat.com> [ Upstream commit 26064d3e2b4d9a14df1072980e558c636fb023ea ] >4GB folio is possible on some ARCHs, such as aarch64, 16GB hugepage is supported, then 'offset' of folio can't be held in 'unsigned int', cause warning in bio_add_folio_nofail() and IO failure. Fix it by adjusting 'page' & trimming 'offset' so that `->bi_offset` won't be overflow, and folio can be added to bio successfully.

[PATCH v3 02/11] platform/x86/intel/pmt: crashlog binary file endpoint

Usage of the intel_pmt_read() for binary sysfs, requires an allocated endpoint struct. The crashlog driver does not allocate the endpoint.

[PATCH v3 01/11] platform/x86/intel: refactor endpoint usage

by Michael J. Ruhl

The use of an endpoint has introduced a dependency in all class/pmt drivers to have an endpoint allocated. The telemetry driver has this allocation, the crashlog does not. The current usage is very telemetry focused, but should be common code. With this in mind: rename the struct telemetry_endpoint to struct class_endpoint, refactor the common endpoint code to be in the class.c module Fixes: 416eeb2e1fc7 ("platform/x86/intel/pmt: telemetry: Export API to read telemetry") Cc: <stable(a)vger.kernel.org> Signed-off-by: Michael J.

[PATCH v3 02/11] platform/x86/intel/pmt: crashlog binary file endpoint

by Michael J. Ruhl

Usage of the intel_pmt_read() for binary sysfs, requires an allocated endpoint struct. The crashlog driver does not allocate the endpoint. Without the ep, the crashlog usage causes the following NULL pointer exception: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: Oops: 0000 [#1] SMP NOPTI RIP: 0010:intel_pmt_read+0x3b/0x70 [pmt_class] Code: Call Trace: <TASK> ? sysfs_kf_bin_read+0xc0/0xe0 kernfs_fop_read_iter+0xac/0x1a0 vfs_read+0x26d/0x350 ksys_read+0x6b/0xe0 __x64_sys_read+0x1d/0x30 x64_sys_call+0x1bc8/0x1d70 do_syscall_64+0x6d/0x110 Add the endpoint information to the crashlog driver to avoid the NULL pointer exception.

[PATCH v3 01/11] platform/x86/intel: refactor endpoint usage

by Michael J. Ruhl

The use of an endpoint has introduced a dependency in all class/pmt drivers to have an endpoint allocated. The telemetry driver has this allocation, the crashlog does not. The current usage is very telemetry focused, but should be common code. With this in mind: rename the struct telemetry_endpoint to struct class_endpoint, refactor the common endpoint code to be in the class.c module Fixes: 416eeb2e1fc7 ("platform/x86/intel/pmt: telemetry: Export API to read telemetry") Cc: <stable(a)vger.kernel.org> Signed-off-by: Michael J.

[PATCH net] gve: Fix stuck TX queue for DQ queue format

by Harshitha Ramamurthy

From: Praveen Kaligineedi <pkaligineedi(a)google.com> gve_tx_timeout was calculating missed completions in a way that is only relevant in the GQ queue format. Additionally, it was attempting to disable device interrupts, which is not needed in either GQ or DQ queue formats. As a result, TX timeouts with the DQ queue format likely would have triggered early resets without kicking the queue at all. This patch drops the check for pending work altogether and always kicks the queue after validating the queue has not seen a TX timeout too recently.

[PATCH] accel/ivpu: Reorder doorbell unregister and command queue destruction

by Maciej Falkowski

From: Karol Wachowski <karol.wachowski(a)intel.com> Refactor ivpu_cmdq_unregister() to ensure the doorbell is unregistered before destroying the command queue. The NPU firmware requires doorbells to be unregistered prior to command queue destruction. If doorbell remains registered when command queue destroy command is sent firmware will automatically unregister the doorbell, making subsequent unregister attempts no-operations (NOPs). Ensure compliance with firmware expectations by moving the doorbell unregister call ahead of the command queue destruction logic, thus preventing unnecessary NOP operation.

by Jacek Lawrynowicz

From: Karol Wachowski <karol.wachowski(a)intel.com> Trigger full device recovery when the driver fails to restore device state via engine reset and resume operations. This is necessary because, even if submissions from a faulty context are blocked, the NPU may still process previously submitted faulty jobs if the engine reset fails to abort them.

[PATCH wireless v1] Revert "wifi: mwifiex: Fix HT40 bandwidth issue."

by Francesco Dolcini

From: Francesco Dolcini <francesco.dolcini(a)toradex.com> This reverts commit 34253084291cb210b251d64657958b8041ce4ab1. That commit introduces a regression, when HT40 mode is enabled, received packets are lost, this was experience with W8997 with both SDIO-UART and SDIO-SDIO variants. From an initial investigation the issue solves on its own after some time, but it's not clear what is the reason. Given that this was just a performance optimization, let's revert it till we have a better understanding of the issue and a proper fix.

[PATCH v3 1/5] drm/dp: Change AUX DPCD probe address from DPCD_REV to LANE0_1_STATUS

by Imre Deak

Reading DPCD registers has side-effects in general. In particular accessing registers outside of the link training register range (0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) is explicitly forbidden by the DP v2.1 Standard, see 3.6.5.1 DPTX AUX Transaction Handling Mandates 3.6.7.4 128b/132b DP Link Layer LTTPR Link Training Mandates Based on my tests, accessing the DPCD_REV register during the link training of an UHBR TBT DP tunnel sink leads to link training failures. Solve the above by using the DP_LANE0_1_STATUS (0x202) register for the DPCD register access quirk.

[PATCH v2 1/2] platform/loongarch: laptop: Get brightness setting from EC on probe

by Yao Zi

Previously during probe, 1 is unconditionally taken as current brightness value and set to props.brightness, which will be considered as the brightness before suspend and restored to EC on resume. Since a brightness value of 1 almost never matches EC's state on coldboot (my laptop's EC defaults to 80), this causes surprising changes of screen brightness on the first time of resume after coldboot. Let's get brightness from EC and take it as the current brightness on probe of the laptop driver to avoid the surprising behavior. Tested on TongFang L860-T2 3A5000 laptop.

Backports for 6.1 and older due to clang -Qunused-arguments change

by Nathan Chancellor

Hi Greg and Sasha, Please find attached backports for commit feb843a469fb ("kbuild: add $(CLANG_FLAGS) to KBUILD_CPPFLAGS") and its dependent changes, commit d5c8d6e0fa61 ("kbuild: Update assembler calls to use proper flags and language target") and its dependent changes, and commit 7db038d9790e ("drm/amd/display: Do not add '-mhard-float' to dml_ccflags for clang") for 6.1 and earlier. The second listed change is already in 6.1 so that series is a little shorter. These changes are needed there due to an upstream LLVM change [1] that changes the behavior of -Qunused-arguments with unknown target options, which is only used in 6.1 and older since I removed it in commit 8d9acfce3332 ("kbuild: Stop using '-Qunused-arguments' with clang") in 6.3. Please let me know if there are any issues, I will try to pay attention for any issues that crop up in the stable review period from these changes but please ping me if you remember. Cheers, Nathan [1]: https://github.com/llvm/llvm-project/commit/a4b2f4a72aa9b4655ecc723838830e0…

[PATCH] pidfs: never refuse ppid == 0 in PIDFD_GET_INFO

by Mike Yuan

In systemd we spotted an issue after switching to ioctl(PIDFD_GET_INFO) for obtaining pid number the pidfd refers to, that for processes with a parent from outer pidns PIDFD_GET_INFO unexpectedly yields -ESRCH [1]. It turned out that there's an arbitrary check blocking this, which is not really sensible given getppid() happily returns 0 for such processes. Just drop the spurious check and userspace ought to handle ppid == 0 properly everywhere.

[PATCH] drm/amdgpu: fix NULL dereference in gfx_v9_0_kcq() and kiq_init_queue()

by Alexey Nepomnyashih

A potential NULL pointer dereference may occur when accessing tmp_mqd->cp_hqd_pq_control without verifying that tmp_mqd is non-NULL. This may happen if mqd_backup[mqd_idx] is unexpectedly NULL. Although a NULL check for mqd_backup[mqd_idx] existed previously, it was moved to a position after the dereference in a recent commit, which renders it ineffective. Add an explicit NULL check for tmp_mqd before dereferencing its members. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Currently, it relies on checking the PTE value to ensure that the moved folio still belongs to the src swap entry and that no new folio has been added to the swap cache, which turns out to be unreliable. While working and reviewing the swap table series with Barry, following existing races are observed and reproduced [1]: In the example below, move_pages_pte is moving src_pte to dst_pte, where src_pte is a swap entry PTE holding swap entry S1, and S1 is not in the swap cache: CPU1 CPU2 userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1 ... < interrupted> ... <swapin src_pte, alloc and use folio A> // folio A is a new allocated folio // and get installed into src_pte <frees swap entry S1> // src_pte now points to folio A, S1 // has swap count == 0, it can be freed // by folio_swap_swap or swap // allocator's reclaim. <try to swap out another folio B> // folio B is a folio in another VMA. <put folio B to swap cache using S1 > // S1 is freed, folio B can use it // for swap out with no problem. ... folio = filemap_get_folio(S1) // Got folio B here !!! ... < interrupted again> ... <swapin folio B and free S1> // Now S1 is free to be used again. <swapout src_pte & folio A using S1> // Now src_pte is a swap entry PTE // holding S1 again. folio_trylock(folio) move_swap_pte double_pt_lock is_pte_pages_stable // Check passed because src_pte == S1 folio_move_anon_rmap(...) // Moved invalid folio B here !!! The race window is very short and requires multiple collisions of multiple rare events, so it's very unlikely to happen, but with a deliberately constructed reproducer and increased time window, it can be reproduced easily. This can be fixed by checking if the folio returned by filemap is the valid swap cache folio after acquiring the folio lock. Another similar race is possible: filemap_get_folio may return NULL, but folio (A) could be swapped in and then swapped out again using the same swap entry after the lookup. In such a case, folio (A) may remain in the swap cache, so it must be moved too: CPU1 CPU2 userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1, and S1 is not in swap cache folio = filemap_get_folio(S1) // Got NULL ... < interrupted again> ... <swapin folio A and free S1> <swapout folio A re-using S1> move_swap_pte double_pt_lock is_pte_pages_stable // Check passed because src_pte == S1 folio_move_anon_rmap(...) // folio A is ignored !!! Fix this by checking the swap cache again after acquiring the src_pte lock. And to avoid the filemap overhead, we check swap_map directly [2]. The SWP_SYNCHRONOUS_IO path does make the problem more complex, but so far we don't need to worry about that, since folios can only be exposed to the swap cache in the swap out path, and this is covered in this patch by checking the swap cache again after acquiring the src_pte lock. Testing with a simple C program that allocates and moves several GB of memory did not show any observable performance change.

[PATCH 21/23] drm/amd/display: Export full brightness range to userspace

by Alex Hung

From: Mario Limonciello <mario.limonciello(a)amd.com> [WHY] Userspace currently is offered a range from 0-0xFF but the PWM is programmed from 0-0xFFFF.

[PATCH 05/23] drm/amd/display: Get LTTPR IEEE OUI/Device ID From Closest LTTPR To Host

by Alex Hung

From: Michael Strauss <michael.strauss(a)amd.com> [WHY] These fields are read for the explicit purpose of detecting embedded LTTPRs (i.e. between host ASIC and the user-facing port), and thus need to calculate the correct DPCD address offset based on LTTPR count to target the appropriate LTTPR's DPCD register space with these queries. [HOW] Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a laptop) will always be addressible using the max LTTPR count seen by the host. Therefore we simply need to use a recently added helper function to calculate the correct DPCD address to target potentially embedded LTTPRs based on the received LTTPR count.

[PATCH 1/2] platform/loongarch: laptop: Get brightness setting from EC on probe

by Yao Zi

Previously 1 is unconditionally taken as current brightness value. This causes problems since it's required to restore brightness settings on resumption, and a value that doesn't match EC's state before suspension will cause surprising changes of screen brightness. Let's get brightness from EC and take it as the current brightness on probe of the laptop driver to avoid the surprising behavior. Tested on TongFang L860-T2 3A5000 laptop.

[PATCH v2 3/4] wifi: ath12k: fix source ring-buffer corruption

Add the missing memory barrier to make sure that LMAC source ring descriptors are written before updating the head pointer to avoid passing stale data to the firmware on weakly ordered architectures like aarch64.

[PATCH 6.1.y] arm64: dts: imx8mm: Drop sd-vsel-gpios from i.MX8M Mini Verdin SoM

by Francesco Dolcini

From: Marek Vasut <marex(a)denx.de> [ Upstream commit 8bad8c923f217d238ba4f1a6d19d761e53bfbd26 ] The VSELECT pin is configured as MX8MM_IOMUXC_GPIO1_IO04_USDHC2_VSELECT and not as a GPIO, drop the bogus sd-vsel-gpios property as the eSDHC block handles the VSELECT pin on its own.

[PATCH stable 6.6.y] arm64: kaslr: fix nokaslr cmdline parsing

by Chen Ridong

From: Chen Ridong <chenridong(a)huawei.com> Currently, when the command line contains "nokaslrxxx", it was incorrectly treated as a request to disable KASLR virtual memory. However, the behavior is different from physical address handling. This issue exists before the commit af73b9a2dd39 ("arm64: kaslr: Use feature override instead of parsing the cmdline again"). This patch fixes the parsing logic for the 'nokaslr' command line argument. Only the exact strings, 'nokaslr', will disable KASLR. Other inputs such as 'xxnokaslr', 'xxnokaslrxx', or 'xxnokaslr=xx' will not disable KASLR. Fixes: f80fb3a3d508 ("arm64: add support for kernel ASLR") Cc: stable(a)vger.kernel.org # <= v6.6 Signed-off-by: Chen Ridong <chenridong(a)huawei.com> --- arch/arm64/kernel/pi/kaslr_early.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/arm64/kernel/pi/kaslr_early.c b/arch/arm64/kernel/pi/kaslr_early.c index 17bff6e399e4..731d0a3f1a89 100644 --- a/arch/arm64/kernel/pi/kaslr_early.c +++ b/arch/arm64/kernel/pi/kaslr_early.c @@ -35,9 +35,14 @@ static char *__strstr(const char *s1, const char *s2) static bool cmdline_contains_nokaslr(const u8 *cmdline) { const u8 *str; + size_t len = strlen("nokaslr"); + const char *after = cmdline + len; str = __strstr(cmdline, "nokaslr"); - return str == cmdline || (str > cmdline && *(str - 1) == ' '); + if ((str == cmdline || (str > cmdline && *(str - 1) == ' ')) && + (*after == ' ' || *after == '\0')) + return true; + return false; } static bool is_kaslr_disabled_cmdline(void *fdt) -- 2.34.1

[PATCH AUTOSEL 6.15 1/9] fbcon: Make sure modelist not set on unregistered console

by Sasha Levin

Here's my analysis: ## Security and Stability Issue This commit fixes a critical **array-index-out-of-bounds vulnerability** that can be triggered via sysfs. The issue occurs when `con2fb_map[console]` contains `-1`, causing `fbcon_info_from_console()` to access `fbcon_registered_fb[-1]`, which is an out-of-bounds array access. ## Bug Analysis The problem is in the `fbcon_info_from_console()` function at line 122: ```c // Before fix: return fbcon_registered_fb[con2fb_map[console]]; // After fix: fb = con2fb_map[console]; if (fb < 0 || fb >= ARRAY_SIZE(fbcon_registered_fb)) return NULL; return fbcon_registered_fb[fb]; ``` ## Trigger Path The vulnerability can be triggered through: 1. **sysfs interface**: Writing to `/sys/class/graphics/fbX/modes` 2. **Call chain**: `store_modes()` → `fb_new_modelist()` → `fbcon_new_modelist()` → `fbcon_info_from_console()` 3. **User-accessible**: This is exploitable from userspace through the sysfs interface ## Code Context from Analysis Based on the git blame, the vulnerable code path in `fbcon_new_modelist()` has existed since: - Original code from **2005** (Linus Torvalds) - The problematic `fbcon_info_from_console()` call was added in **2022** by commit `409d6c95f9c6` ("fbcon: Introduce wrapper for console->fb_info lookup") ## Risk Assessment 1. **High Impact**: UBSAN array bounds violation, potential for memory corruption 2. **User Triggerable**: Accessible via standard sysfs interface 3. **Long- standing**: The vulnerable pattern has existed since 2022 when the wrapper was introduced 4. **Active Exploitation**: Reported by syzbot, indicating active fuzzing found this issue ## Backport Suitability 1. **Small & Contained**: Only 6 lines changed in a single function 2. **Safe Fix**: Adds bounds checking without changing logic flow 3. **No Dependencies**: The fix is self-contained and doesn't require other commits 4. **Clear Bug**: Definitively fixes out-of-bounds access with proper NULL return 5. **Stable Pattern**: Callers already handle NULL returns from `fbcon_info_from_console()` ## Comparison to Historical Precedent Looking at the similar commits provided: - **Similar Commit #1** (Backport Status: YES): Fixed boundary checks in fbcon parameter parsing - this follows the same pattern of fixing bounds issues in fbcon - The other NO commits were architectural changes or refactoring, not security fixes This commit perfectly fits the stable tree criteria: it's an important bugfix, has minimal regression risk, is contained to a single subsystem, and fixes a user-triggerable vulnerability. drivers/video/fbdev/core/fbcon.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/drivers/video/fbdev/core/fbcon.c b/drivers/video/fbdev/core/fbcon.c index ac3c99ed92d1a..2df48037688d1 100644 --- a/drivers/video/fbdev/core/fbcon.c +++ b/drivers/video/fbdev/core/fbcon.c @@ -117,9 +117,14 @@ static signed char con2fb_map_boot[MAX_NR_CONSOLES]; static struct fb_info *fbcon_info_from_console(int console) { + signed char fb; WARN_CONSOLE_UNLOCKED(); - return fbcon_registered_fb[con2fb_map[console]]; + fb = con2fb_map[console]; + if (fb < 0 || fb >= ARRAY_SIZE(fbcon_registered_fb)) + return NULL; + + return fbcon_registered_fb[fb]; } static int logo_lines; -- 2.39.5

[PATCH] sysfb: Fix screen_info type check for VGA

by Thomas Zimmermann

Use the helper screen_info_video_type() to get the framebuffer type from struct screen_info. Handle supported values in sorted switch statement. Reading orig_video_isVGA is unreliable. On most systems it is a VIDEO_TYPE_ constant. On some systems with VGA it is simply set to 1 to signal the presence of a VGA output. See vga_probe() for an example. Retrieving the screen_info type with the helper screen_info_video_type() detects these cases and returns the appropriate VIDEO_TYPE_ constant. For VGA, sysfb creates a device named "vga-framebuffer". The sysfb code has been taken from vga16fb, where it likely didn't work correctly either. With this bugfix applied, vga16fb loads for compatible vga-framebuffer devices.

[PATCH v3] video: screen_info: Relocate framebuffers behind PCI bridges

by Thomas Zimmermann

Apply PCI host-bridge window offsets to screen_info framebuffers. Fixes invalid access to I/O memory. Resources behind a PCI host bridge can be relocated by a certain offset in the kernel's CPU address range used for I/O. The framebuffer memory range stored in screen_info refers to the CPU addresses as seen during boot (where the offset is 0). During boot up, firmware may assign a different memory offset to the PCI host bridge and thereby relocating the framebuffer address of the PCI graphics device as seen by the kernel. The information in screen_info must be updated as well. The helper pcibios_bus_to_resource() performs the relocation of the screen_info's framebuffer resource (given in PCI bus addresses). The result matches the I/O-memory resource of the PCI graphics device (given in CPU addresses). As before, we store away the information necessary to later update the information in screen_info itself. Commit 78aa89d1dfba ("firmware/sysfb: Update screen_info for relocated EFI framebuffers") added the code for updating screen_info. It is based on similar functionality that pre-existed in efifb. Efifb uses a pointer to the PCI resource, while the newer code does a memcpy of the region.

[PATCH 1/4] drm/dp: Change AUX DPCD probe address from DPCD_REV to LANE0_1_STATUS

by Imre Deak

Reading DPCD registers has side-effects in general. In particular accessing registers outside of the link training register range (0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) is explicitly forbidden by the DP v2.1 Standard, see 3.6.5.1 DPTX AUX Transaction Handling Mandates 3.6.7.4 128b/132b DP Link Layer LTTPR Link Training Mandates Based on my tests, accessing the DPCD_REV register during the link training of an UHBR TBT DP tunnel sink leads to link training failures. Solve the above by using the DP_LANE0_1_STATUS (0x202) register for the DPCD register access quirk.
